The code gives a parse error I can't find what the error is, the curlys brackets aren't wrong I'm trying to model the equation, v = sqrtfrac{19.6mass}{Cd1.229*area}
<?php
function terminalVelocity($mass,$cd,$area) {
$velocity = (sqrt(19.6 * $mass / $cd * 1.229 * $area));
return $volume;
}
if ($_POST['enter']) {
$mass = ($_POST['mass']);
$area = ($_POST['area']);
$cd = ($_POST['cd']);
if ($mass > 0 && $front > 0) {
$result = terminalVelocity($mass,$cd,$area);
echo "The terminal velocity of the is: ". round($result,2);
} else {
echo "You must have a value for each input";
}
?>
